Be it known that I, JOHN W. SCHATT, a citizen of the United States, residing at G05 Wanda, in the county of Cattaraugus and State of New York, have invented certain new and'useful lmprovements in Piercing v Tools; and I do herebydeclare-the following,

to be a full, clear,

and exact description of the invention, suchas enable others skilled in the art to which, itap'pertains to This invention relates to tools and particularly 'totools for piercing or forming a ertures in any desired material and one t at readilyent'er-and out or material without fpreviousl'y 1 punching the ma be foldedinto a handle for rotection an for being at all times out o the way when notinuse. Y

The invention comprises the provision of a tool secured in a handle of a pocket knife, and as a substitute for one of the blades thereof so that the tool may be moved into the handle and'outagain in the manner of an i; ordinaryjblade.

The invention further comprises the rovision of a tool'formed arc-shaped or su stan- 'tially arc-shaped in a cross-section so as to pierce any desired material anyother implement and to evenly cut a proper sized be e.'-

Theobject- H1 view is the provision of a tool designed'tdenterand cut a-smooth hole in a belt or other inaterial and to soarrange the-tool as tobe'capable of folding into a handle' in the manner of an ordinary "bla de of'po'cket knives so that the tool may be brought into operation at any time and "then again -moved out of the way after been used. 1

With these and other objectsinjview the invention comprises certain novel constructions, combinations, and arrangements of parts, as will be hereinafter more fully described and claimed.

be easily and conveniently retained near the ed and yet to provide a structure that may person so that the engineer or other person using the same may have ready means at hand for repairing'purposes when needed. In the present invention these desirable ob jects are designed to be attained, as by the arrangement of the tool which takes the place of one of the blades of a ocket knife, a structure is lpresented in whidli all the ade ordinary punch is secured and in addition the advantage of a pocket knife that will act either as a knife or as a piercing tool at the option of the possessor. The tool accomplis e piercing or punching io era'- tion Without the assistance of any auxi iary means.

Referring more particularly to the draw ing, 1 indicates the handle of a pocket knife of any desired kind to which is secured a tool or punch 2 The tool 2 is held in place as an ordinary blade and takes the place ofone of the blades usually positioned in handle 1. In

constructing the tool 2 the same is preferably made arc-shaped asclearly seen in Figs. 3

'and 4. The outer surface is struck on the as a left-handed person rotates an article in one direction While a right-handed person usually rotates an article in another direction, so that by the construction of applicants tool, as seen in Figs. 3 and 4, the same will easily cut a hole in leather, brass and other comparatively hard material, regardless of the direction of rotation of the tool.

As clearly seen in Fig. 2 the tool is not only crescent-shaped but is also tapered and runs to a substantial point 5. It will be observed that point 5 is not a sharp point but is slightly rounded. This will permit the tool to begin. to cut from'the instant it touches the leather until the hole is completed. If the point were 'sharp,-that is, pointed like a'needle, t would re uire a certain amount of force to compel t etool to enter the leather and would require a continued force as the tool ropler is also aimed to thoroughly progresses through the leather. By this construction the end 5 begins to cut as soon as the tool is put into operation so that the tool cuts in its forward movement as well as cuts alon the edges '3 and 4.

Prefera ly the tool member 2 is made of very fine steel and comparatively thin and in order toproperly fit the same in an ordinary size handle, as seen in Fig. 1, a filling or reinforcing block 6 is provided for thickening the shank of the tool where the same enters the handle. The shank 6 may be riveted or sweated to the shank of tool 2 as may be desired so as to firmly hold the same together.

. The end 7 of the shank 6 and also of the tool 2 is preferably rounded on the arc of a circle so that when the tool isJopened it will not be in position for operation until entirely opened as seen in Fig. 1. This will 'prevent the attempted use of the tool when it is only half opened and projecting at a ninety degrees angle from the handlel. It will be evident that although this is the preferred construction the shank at point 7 may be square as in the ordinary shank of a knife.

In operation when it is desired to punch a hole through a piece of leather, bone or other material, the tool is moved from its closed,

position in handle 1 and then point 5 is pressed against the article through which the hole or aperture is designed to be made and the tool is rotated. During the rotation the tool is slightly pressed inward for feeding the 'same forward. As the tool progresses the end 5 will cut for ermitting easy progression through the artic e and the sides 3 or 4, as the case may be,-will cut the sides or walls of the apertures being formed. It will be observed that by this construction the sides will be cut and not scraped. The continued increase in diameter of the tool will cause the same to permit the cutting edges to engage the Wall of the aperture and also the particu- -lar curved or arc-shaped constructlon will assist so that a sharp cutting or shearing actlon 1s glven. hole or aperture .of any desired size so as to permit t e easy securing together of belts and the like and will provide holes therefor that are not ragged or split or torn. By pivotally securing the toolf into a handle as 1,

o the same is provided with a handle or supporting member that will easily permit the forcing of the tool in its work and will also provide a convenient shield and protection orthe tool when not in use. Also by arranging the tool 2 as a substitute for one of the blades of a pocket knife the tool is always convenient an at hand in case of sudden breaks, as the same may be easily carried by the engineer or other person who has charge of the repairing work. It will also be evi- This will cut a smooth, roundpurposes than punching belts Within the spirit of the invention and that the placing of the same'in the handle ofan ordinary pocket knife provides a combination of pocket knife and piercing tool 'thatwill be convenient in many vocations.

One form of the invention has been specifically described order to clearly set forth an operative structure, but it is'to be understood that any changes, modifications, and variations within the spirit of theinvention isclaimed. The tool is designed'among other things to be used as an emergency tool and is practical for many professions, particularly so in the electrical line when lercing or forming apertures in asbestos sheets, through wall laster, laths, plate copper, or any part of e ectrical work put .up by the electrician. The tool-is-also designed to be. used in iercing or formingholes in pearl, bone, and the like,.and',is also designed to be used by mechanics, firemen, engineers, and all persons that find'it necessary at various times to pierce or form holes in leather, steel,

tial crescent in cross section makes the tool a self-sharpening instrument, and its cutting cutting through copper or bone, as the contact of the outer sur ace of the tool with the material being pierced keeps the cutting edgesharpenedi .In use as a punch forv unching edges are therefore not dulled in the least by v belts, harness, or leather requiring oles, the

instrument is very ractical as various size holes may be quic y and easily cut by the same tool without'tearing the leather being punched.

What I claim is: 1. A piercing tool comprising a handle, and a plvotally mounted cutting member,

said cutting member being beveled from 0 e end to the other andformed substantial y crescent shaped in cross section with cutting edges on each side thereof, having its shank reinforced by a block of sufficient thickness to protect said edges when the cutting member is swung upon its pivot into said handle.

2. A piercing -tool com rising a handle,

.and a cutting member, sai cutting member being beveled from one end to the other, and bent substantially crescent-shaped in cross section, and formed with a cutting edge on each side thereof.

In testimony whereof I aflix my signature in presence of two witnesses.
